That leaves me with 5% to come from my own pocket.

Here are some general guidelines: Lien Position1st Position LienEquityMinimum Down Payment of 20-25% (a 30% equity to sale price is preferred)Down Payment made in certified funds and not borrowedMaximum Funding of 70% ITV (Investment to Value)SeasoningMinimum of two monthly payments already made12 months or more preferredPayer CreditCredit Score of 650 or higherNo major derogatory trade lines (No 90-180+ days delinquent, foreclosure, repossession, bankruptcy, etc.)No decline in credit since purchase of businessTermsPrefer 60 months or lessMaximum of 72 monthsNo Balloon Payment preferredCash FlowBusiness has positive cash flow1.25 debt service coverage ratio preferred.DocumentationPersonal guarantee from a creditworthy individualStandard documents including Note, Security Agreement, and UCC-1 filing.Tax Returns on the business that substantiate profit and loss statements.OtherPayment history current and verifiablePayer Interview indicating buyer is satisfied with business and comfortable making paymentsMotivation for selling the note is not a result of a deteriorating businessConsideration of high risk businesses or geographic areasIn these situations, sometimes a partial is a better option. 

I'm wondering if a more budget-friendly option, like the RHEEM water softener (42,000 Grain Preferred Plus Water Softener for Hard Water and Iron Reduction) available at Home Depot for around $500, would be sufficient.Has anyone had experience with similar DIY water softeners?

In this instance what I would do is get the deed in lieu from the borrower so you ahve the property again and get a note from them but have an attorney draft it to see if you can include a confession of judgment - meaning if they do not pay then you can get a quick judgment and possibly garnish wages.I would also have them put a small down payment as part of the note and only accept a check that way if you ever did garnish you have a copy of a check so you know where they bank.unfortunately you are right they can stop paying on the note and its unsecured so its a risk but out of all the options this is your best option.

THEN, I plan to purchase the second home using a FHA or conventional loan (3%-5% down), for which I will likely pay the monthly cost out-of-pocket, maybe with some rental income support if it is a duplex.My concern is, I do not want to spend my savings or weigh down my debt-to-income ratio so much so that I cannot qualify for and pay the down payment and closing for the lending on the second home.Questions: - With the first home being multi-family, 75% of the rental income (or potential rental income initially) will relatively either maintain or boost my debt-to-income ratio from lenders' perspectives, right? 

Paying this out of pocket is going to hurt badly after I've already lost rent for the past 6 months plus court fees.

Ideally, the best option from a financial point of view would be to go through a local community bank.

.: I'm probably the only one on Bigger Pockets on a Saturday night, but was reading Avery Carl's "Short Term Rental, Long Term Wealth" and my mind is churning as usual.

I am absolutely focused on networking at this stage as I devour books, and glad I found bigger pockets. 

In 2021 I began listening to bigger pockets podcast episodes religiously and got the real estate bug.
