My strong suggestion would be to look at non-leased land condos. Rents in mobile home parks are really high and only destined to go higher. Also, a mobile home depreciates whereas a condo will appreciate (in the long run). The savings on the price of most leased land condos are, quite often, more than lost in the monthly land lease payments. Not to mention the fact that lenders really frown on leased land AND mobile homes.
At 25K per year, you're going to be hard pressed to afford to buy much of anything in Huntington Beach. There are, currently, nine condos at or under $200,000. Only two of these are not on leased land and are both 1 bedroom, 1 bath units of 593 and 650 square feet. Also, both are in a 55 and over community so, if you aren't 55 or over, you can't live there anyway.
Of the 7 on leased land, one (on Delaware) doesn't show the lease cost but is listed at $54,900 and is a 55+ community. Two show leases of $2,520 and are in the Huntington Harbor area. They are listed at $144,900 and $150,000. Lastly, the other four show leases of from $7,403 to $7,880 and are listed from $95,000 to $174,900.
Give me a call (714-552-2335 or email Tim@TimKunze.com) and we can crunch some numbers. It would also behoove you to get together with a lender - I can recommend several - and find out just what you can afford. If you can find an FHA approved condo, you can get in with as little as 3% down.
