I'm sure my cash flow could vary based on the loan I would receive since I could use a first time home buyer loan but lets assume that I use a 30 year fixed FHA mortgage at 7%. 

I work in tech so I'm naturally gravitating towards areas that have a lot of tech workers (lots of foreign workers renting).Any ideas? 

We take this to mean (based on 100s of real tax court cases) any activities integral to the business of running a rental.

I just purchased my first property in Forth Worth to flip and I am based in Houston.

Hey @Felix Shi, your decision really should be based on your risk tolerance and goals.

Do mobile homes have a "book value" based on make/model, size, condition, etc. and if so, where can that information be found? 

I recommend investing near economic bases near downtown and surrounding areas.

You have to calculate based on a more than a few things like loan amount, down payment, taxes, Insurance, (Any HOA) PMI, based on credit, etc.If you are 1099 the Bank can look at the most recent 1099/Schedule C if you have been in business for 5 years or more with a 25% ownership in company or more. 

Naturally, some of the COVID era high rental growth darlings such as Phoenix and Tampa have gotten caught in the mix.Conversely, markets with low supply, including some in the Midwest, saw rent increases of over 3%.

Based on the train of thought you shared you are completely ignoring a critical piece of the equation which is your own capabilties and whether you have the ability to execute on the opportunity.
