Good question - and a very wise decision to put the money into a home, rather than pay rent. You will likely find that there are a number of homes and condo communities in you rarea that fit the bill. One thing to keep in mind is that a one bedroom condo is often a more difficult resale (people just like the extra BR).
The other info is very solid, and I think I would charaterize the process this way:
1) get pre-aprroved for a mortgage (this is VERY important toi the process and helping you determine what you can afford and should be looking at). You also need to consider how much you will be using as a downpayment (at least 20% is recommended).
2) Begin researching homes on your own through all kinds of online sites (Realtor.com, etc) to determine what you like that is in your price range.
3) Research agents and intrview them - you are hiring them, and you want someone who is patient, a good listener, understands your needs and can offer the help and guidence you need. Ask friends, family, and neighbors who they used and if they liked them. (Your agent's commission is paid by the seller, so there is no point in not having one).
4) Once you find the home you like with your agent, have the agent research recent slae prices for similar homes in the areas (called "comps") and submit what you feel to be a fair bid based on the condition of the home and differences from the comp homes.
5) The seller will review your bid and either accept, counter offer, or reject it. You can then accept or counter offer their conter offer. Once you agree on a price, you both sign an agreement of sale - this is a contract that binds you both to the sale, pending an inspection.
6) Get a home inspeciton, and DO NOT waive any inspections (like termite, radon, etc). Reaserch and interview inspectors and hire the one that is the best for you. Your agent may recommend some, but it is always wise to research them online (with Angie's List or the BBB, or via a Google search for your area) to see what services are available and what different inspectors have to offer (You hire and pay the inspector). Get all the appropriate and needed tests and inspections (you will have to hire someone for each - many inspectors offer them all as "one stop shopping"), since this is your opportunity to negotiate with the seller to have items repaired, insects treated, and radon mitigated at Seller Expense. Typically in PA, you have 15 days to have all these tests and inspections performed and respond to the Seller with items you would like to have corrected or treated (this is where many agents REALLY earn their commission). Sometimes the seller will fix them, other times they will give you money back so you can have them done your way by your contractors. Expect to pay about $300 for a standard townhome inspection, $75 for a termite inspection, and $125 for radon testing (on average in PA).
7) You will need an appraisal. Typically, the lender hires the appraiser and you never see a copy although you wil be charged for it in closing costs.
8) Review the Good Faith Estimate from the lender to determine what your closing costs will be and start setting aside money for it if you have not already. (and bring the finds to closing the the form of a Certified Check - personal checks are no good at closing).
9) Sign the closing papers and move in!
There are some steps I glossed over and may have missed (this is a basic outline), but it should help get you started!!
