Go wtih what works - but intelligently.We offer a free month of rent, but to avoid desperate people, we credit 50% towards their 2nd month (to make sure they can afford 1st month rent + SD) and then credit the other 50% the 5th month.

Many note funds take on debt from larger lenders or lines of credit against their assets.

Developers will not be able to get these bonus building permits without providing such TDR credits.  

If I have several options, I would prefer a HELOC with no initial draw requirements (i.e. to establish a literal line of credit that I have no specific short term plans to use), i.e. not something like the better.com HELOC. 

I'm wondering if a BLOC could help to build my business credit.

I've been self-employed for only 6 months, and loans are proving difficult to come by despite my great credit (not to brag, I'm moreso frustrated and seeking help).

Many community banks will give you credit for proforma rents.  

Any local bank that does this kind of financing should be able to approve you as long as you have a good enough credit score and never declared BK.

Quote from @Jaycee Greene: Assuming you pay asking price, I'd estimate the down payment for something like that using a hard money loan (HML) would be around 40% of the purchase price and your monthly payment would be $2,600 with an interest rate in the low 7% range (probably need a 700+ credit score to get that).

The major issues come to play as James pointed out when there is lack of disclosure to the seller and a note does get called and puts them in a terrible position.
