I know not typical on here to have such a little amount in loans but we enjoy great cash flow that we live on, have lots of flexibility in what we can do and have no concern about making payments if the economy were to take a dump.

My two single family houses typically get rented out as mid term rentals under airbnb which offers good coverage and we have been happy with.

W what typically went wrong in your case? 

However, we typically use the FHA-203k loan because it involves a renovation, which I highly recommend if you are looking to really boost your equity and have the cost of the renovation wrapped into your loan with a VERY LOW AMOUNT OUT OF POCKET.I like the FHA loan, but honestly, the Fannie May Home Style is an even better product at this point because you just have to bring a bit more cash to the table 5% vs. 3.5% (w/ FHA), but you have a bit more flexibility.  

What else should I be working on in the meantime prior to listing the lots for sale to get ready for this sort of transaction?

. $300k loan needs to show $15k liquid assets, and draws typically require you to pay contractors and obtain a lien release before you can be reimbursed for the money you paid contractor.While I know there are a lot of people who use low money down loans to get started, it is risky.  

Buying a mobile home to place on your land can be a great way to generate rental income, but like any investment, it comes with pros, cons, and key considerations.On the pro side, mobile homes are typically more affordable than traditional single-family homes, meaning lower upfront costs.

Deduct NEW property taxes after you buyDeduct home insurance costsDeduct maintenance percentage, typically 10%Deduct vacancy+tenant nonperformance percentage(we recommend 5% for Class A, 10% Class B, 20% Class C, good luck with Class D)Deduct whatever dollar/percentage of cashflow you wantNow, what you have left over is the amount for debt service.Enter it into a mortgage calculator, with current interest rate for an investment property, to determine your maximum mortgage amount.Divide the mortgage amount by either 75% or 80%, depending on the required down payment percentage - this is your tentative price to offer.If the property needs repairs, you'll want to deduct 110%-120% of the estimated repairs from this amount.Be sure to also research the ARV and make sure it's 10-20% higher than your tentative purchase price.As long as the ARV checks out, this is the purchase price to offer.It is probably significantly below the asking price.

You typically get the monthly payments but also backed by portfolio and not one note.

For the security deposit, let them sort that out.
