While this simplifies billing, it may not be the most transparent or equitable solution.I'd greatly appreciate any insights, experiences, or alternative solutions that members of the community have to offer.

In areas that are very tourist-desirable, like coastal/beachfront resorts in FL tiny homes can provide an alternative to higher priced hotel rooms and attract a younger clientele that is not looking to book the large (sleeps-12-at-a-time) condos.

Interesting alternative.

It could feel like being stuck in a rat race.A better alternative is to explore books and podcasts from sources like Bigger Pockets.

You need framing details for any alternations to the floor plan.

What are the most promising alternative lending strategies for financing RE developments given the rising interest rates and tightening credit conditions?

Below are some general notes on DSCR loans:* usually used for single family or 2-8 multi family unit properties (fits your scenario)* must be for investment, non owner occupied (if looking for a product for alternative qualifying solutions for owner occupied there are other products)* can close in a personal name or LLC* usually 80% LTV for a purchase (20% down payment) & usually 75-80% LTV for cash out refis* prepayment penalties vary and are optional, but the higher the prepayment penalty, the lower the rate / options typical range from no prepay all the way up to 5 year prepay and structures vary for how those penalties work (3 year is my most popular by far)* appraisal most likely required and paid out of pocket during transaction* can be used for long term, mid term, or short term rental properties * generally 1%+ is the desired DSCR ratio but you get better rates if the ratio is higher (usually rate breaks kick in at 1.15%+ or 1.25%+) and you can still get the loan done if ratio is lower than 1% but the rate will reflect that (DM me if you wand help learning how to calculate the ratio)* the average time to close is 21-30 days* fees vary lender to lender and product to product, but $1595 underwriting plus title fees is pretty standard* 700+ credit is preferred to get max LTV, but plenty of options if credit falls below that* a typical loan minimum is $75k (have limited options for $50k+) and typical loan maximum is $3-4m (have limited options for $4m+)* 3 months reserves usually required, having 6+ months will usually result in better loan terms, 0 reserves can still get the job done if you go with a program that allows you to use the cash flow as reserves* 30 year fixed, IO, and ARMS available

The question is alternative use of equity compared to current use.  7.

Is there an other alternative ?

The BRRRRR is not dead and value add investing will always make sense when one looks at alternatives.
