There are any number of Real Estate schools available to you, so choose the one that compliments your learning style, whether that be online or in person or a hybrid. 

Generally speaking, with SFR or small multis, I just rely on the lease/rent roll (and some form of proof of payment; i.e. bank statements, deposit receipts, tax returns, etc.). 

If the property is solely tenant occupied you will be looking for a Dwelling/Fire Policy (may be called a Landlord policy or similar name) or a commercial policy such as a Business Qwners or Package policy.Most homeowners or dwelling/fire policies include:1.

You can find some 2 units under or around $250K but they have been sitting on the market for over 150 days which tells you its not a great deal if it were an investor woud have already purchased it 4 month ago.  

Or add an extra garage.  

@Ryan WasherHey everyone, I'd be interested in attending an in-person or virtual meet up also.

Or even a paper calendar? 

Hi @Raymond Kalonji I would follow what all have said here, but I want to highlight one thing while working with section 8 or any other tenant is very important "timely communication".

The way I interpret the following policy clause is that so long as the property is defined as other than "VACANT" which is the case when the property is being "constructed, altered or repaired", the 30-day time period and vacant status does not apply in this instance: We do not insure any loss at your premises if your dwelling has been vacant for more than 30 consecutive days immediately before the loss and the declaration page indicates an occupancy other than “VACANT“.

Use a DSCR loan (or conventional if you can qualify).
