I am looking for a RE financor/investor to lend me the amounted fix money we agree to buy the property for, and in exchange I will pay the investor a 6.3% interest by distributing monthly passive income to them in a duration of 15 years.Using the deal that I currently am seeking for now, This Fourplex is listed for $459,900. i plan to negiociate down to AT MOST $409,900 (50K less than asking price).

https://www.donotcall.gov/report.html I am getting so many text messages, both political parties as well as from people wanting to buy my home...

Once I get the homeowner to sign the assignment,  do you want to be the first option to review the numbers and possibly buy ?

In the webinar, he stated he's been buying/selling MHP for over 5yrs and just recently he and his partners started the investment group. 

How long ago did you buy?

Bottom line is buy as big as you can reasonably buy once you are out of small multifamily. 

BiggerPockets also has a calculator to analyze deals, and I highly recommend you start this as soon as possible, even if you are not ready to buy.

For example how much is the full purchase of the property you're looking to buy?

@Amir PortalRecommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

Things they did bad which I wish I had asked more information about:Never involved in the screening of tenantsThey recommended keys for cash by waiving the rent amount buy only collecting fees which they would get not meThe cost to evict is 750-950 yet other companies told me they will include eviction in the priceThe tenant didnt pay in full last month and I was the one calling out to them and asking questions then a few days later I get an email saying something happened with the tenant and they are investigating.You get passed from person to person every week or so.No one told me when the construction was complete and so the house was ready for a week and the post to zillow and other sites was not done.It took them another week to take pictures and then another week to upload it.I was paying 200 dollar a month electric bills while the house was vacant because they left the AC running in the empty property.
