I've also been looking at the Affordable Loan Solution® mortgage from BOA (3% down, no mortgage insurance required), but I guess that loan has restrictions, such as the "borrower’s income cannot exceed the area’s median income" (somebody told me this restriction...still need to do some more research on it).I guess I'm worried that the PMI of the FHA loan will end up causing me more harm than good.

Hi @Ashley Ramirez,I would suggest you getting the Profit First - Profit First: Transform Your Business from a Cash-Eating Monster to a Money-Making Machine. 

The paperwork required for tenants, the headaches and waiting periods that owners are seeing etc.During the past seven months of the pandemic, the majority of single-family property tenants managed to remain current with their rent payments, according to a nationwide survey released today by the National Association of Residential Property Managers (NARPM®).

This comes right off of their website.2019 Code of Ethics & Standards of Practice"REALTORS® shall not acquire an interest in or buy or present offers from themselves, any member of their immediate families, their firms or any member thereof, or any entities in which they have any ownership interest, any real property without making their true position known to the owner or the owner’s agent or broker.

If you can keep up that cash flow you have found yourself a real machine!

To someone in the midwest they consider it nasty to have to share laundry machines with other people & some would just never consider renting a place without laundry in unit. 

While it goes without saying that finding deals is the most important aspect of the business my question would be what is the number one tool or system to have in place to sustain a well-oiled machine and business that could potentially be sold at a later point in time.

For anyone in maryland I'm looking up this house I want to wholesale and Deal Machine gives one price and zillow gives another which one is accurate?

Current gross rent is $3435 plus $150 per month from coin operated laundry machines for the tenants.

The numbers are only going to get you so far.The numbers won't tell you if your GC is going to flake out and disappear three weeks into this rehab, if this dubious person hired a trim carpenter who doesn't know how to cope inside corners, if your flooring guy's going to assure you that of course there's no problem with having vinyl flooring in the kitchen of a home that you intend to sell for over half a million dollars, if you have plans on replacing those Lowes bargain bin flushlights in the kitchen and hall with something else, if your drywall guy will eventually tell you that, sorry, he knows nothing about plaster repair in structures dating from the 1920s, if that ceiling in the living room is popcorn, painted popcorn, asbestos-laden old painted popcorn, or just a knockdown texture finish, why there is a washing machine in the kitchen, and the hits just keep on comin'...Get in the weeds of the rehab analysis, Alon.
