If you buy it as an Owner/Occupant, you will put less down and have a lower rate, but you will probably have a clause about being an Owner/Occ for at least two years: If you violate that clause, the consequences could be tremendous.
If you buy as an Investor, you will have to put at least 20% down and you will have a higher interest rate.
Consider all this.
I have a great property search on my website (PortCityRealty.com) that you are welcome to use. It is a live search from the Baldwin Multiple Listing Service. You can search for properties for sale. You can also search for properties for rent to get an idea of the rental rates.
Please give me a call via my profile (click on my picture) so I can get the information necessary to see what's available that will fit your budget and overall goals. I can e-mail listing details and save the search criteria for automatic notifications so you stay on top of what's happening in this specific market. People are competing for what they want again, so getting immediate updates can make the difference in having a chance at what you want or missing out completely.
I'd be honored to assist you in any way I can.
The key will be the selection of the home you want to retire in, will it be the home that also makes the best rental? If you select a brick home on slab, 3 or 4 bedrooms with at least 2 baths valued between $140,000 to $275,000, then you should will be able to rent it quickly with a good rental rate.
