The "zero-down, take-over-my-2.5%-mortgage" is a unicorn example that he likes to throw out there as bait for all newbies to buy into his program.  

Should I go on my own or seek employment with a Title/Mortgage Office?

A new to the area 20 something with a strong local employer may be a more long term occupant. 

I’m currently self-employed in construction making around $60k a year with an additional 40-50k coming from my investment property.Appreciate any insight from the community.Thank you.

In which case you may be better off cutting bait and doing something on your own rather than waiting for them to make more mistakes.On the other hand I'm curious how they are going to pay you off with such a great return if they are under performing?

Some things that make a rental appealing 1 - pet policy (pets or no pets allowed)2 - number of full bathrooms 3 - number of floors (single level vs multi)4 - backyard or lack thereof5 - school ratings (higher the better)6 - crime ratings (lower the better)7 - location to highways8 - amenities (parks, pools, trails, lakes, etc)9 - location to place of employment.10 - age of the property 11 - appliances Just to name a few.

Population is growing aggressively and jobs are moving here especially with major employers like Intel, Google, Amazon, Nationwide, etc.

Thanks Conventional loans will underwrite your entire income with your paystubs, W-2, and tax returns (if you have any self employment income, and own other real estate).

There may be potential self-employment taxes.

If it turns out to be really serious, like described above, then you can renegotiate with the seller and/or cut bait.
