I mainly want a site that offers advertising the property, online payment options, maintenance requests & at least a basic accounting aspect.Thank you in advance!

I can do this by networking, hosting a monthly meetup for investors, and offering a coaching program.How about you?

I understand the rate is competitive on the assumable, but having $300k liquid, you might as well do a lower downpayment and Buy down the rate. 

Depends on really what you are looking for:-Speed - some HMLS can go "no appraisal" so can close very quickly and beat cash offers if you are in a competitive market to buy-Interest Rates - can range anywhere from around 8% to 13% (same with "points") but not usually as huge of a concern for flippers since the terms are so short-Leverage - depending on your risk appetite / capital - this is also a top concern for some (almost always over and above rates/fees) can see anywhere from around 80% LTC to even mid 90s LTC (including 100% of rehab budget)

I like the product but their policies drowning them down in competition.

-- Also, if they are really pushing this as a benefit, what type of guarantee are they willing to offer to back it up?

Another would be when a lender or bank offers you the cash to buy the home and they cross collateralize one or more homes to bridge the gap of equity needed.

Interesting to see how feasible this will be. 

I identified a nice cabin in a nice area that I was going to offer $500k to STR it.

I was wondering if anyone here can offer some guidance.
