I purchased home with a traditional 30 yr mortgage (4.75%).

I figure that to get tenants it’s best to post on several platforms and I recently found zumper but can’t find any outside information on how it is for landlords.

@Nicholas Mann pretty much @Abel Curiel has it covered here... your other option here is to throw two realities at them... one in which they get a comfy number, but on terms you like, so maybe $580k, but they do a seller carryback for a monthly rate of significantly less than your current financing options are giving you so that you cashflow heavy immediately, or $480k on traditional finance.

We want to refinance in July to a traditional mortgage.

Also, airbnb competes with the traditional hotel industry.

Would I be able to use the Mobile Home that comes with the purchase as consideration to make it a traditional investor type loan? 

I financed this deal using traditional portfolio loan with a local bank and for the equity I used a line of credit in which I leveraged another investment property towards.

I wouldn't say it's impossible to make it work in the Dallas market out of state, but prices have been creeping fast which make it harder to do a traditional rental where the numbers work.

Thanks for the advice , I originally was primarily focused on small multi families but thought the cash flow would not be there / rental appeal outside of the more traditional urban area of Hartford.

You also can definitely go the traditional route with 3.5% down and buy of the MLS too, but remember that FHA will only lend on what the property will appraise for, and it very often will come in lower than asking price in a hot market, so be prepared.
